On 19 October 2017 an Interstellar Object was spotted passing through our Solar system, the first of its kind to be discovered. With little warning, astronomers had only a few days to study it before it became too faint for detailed investigation, even when using the world’s largest telescopes. Studies revealed a body that matched some of our expectations, but that differed significantly in other aspects. This talk will cover how it was discovered, and what we have learned so far.

Doors open about 7.15pm. There is free parking available on the campus in the evenings. Admission Free, including light refreshments. We are located in the Bell Theatre, Department of Mathematics and Physics, QUB - details here......
